Have you been talking to a Mr Trump?
It sounds a bit like his America first policy. America has the resources to do that, but not the will. If an item costs £1 and a very similar one £5, which one will be more popular with the consumer?
It's not just China you need to watch. If/ when you next go to a supermarket, have a look at where the fresh herbs and fruit come from. It can't be that countries in Africa are the only places able to grow coriander or chives. If you can crack the global trade conundrum, you'll be some way to reducing global warming as well.
If you wish to boycott China, that's great. But you may have a hard time working out if your shirt, that was stitched in Thailand, using cotton from India, uses buttons from China, for example.
